specific gravity to density calculator

SG = Specific Gravity (at 60 o F) Specific gravity can be calculated from API gravity: SG = 141.5 / (°API+131.5) (2) Note! This is why we take the value for specific gravity of cement 3.15. The density will be displayed as a specific gravity ratio in the lower text box. Density, Specific Gravity Definition: Density and specific gravity have very similar, but not quite identical definitions. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 o C. Because specific gravity is a ratio, it is a unitless quantity. Mollier diagrams included. Density … Bulk Specific Gravity Calculator. The Specific Gravity for Solids and Liquids equation (SG = ρ / ρw) computes the Specific Gravity (SG) of a substance based on the ratio of mass density to density of water under standard conditions (4ºC). Relative density, or specific gravity, is the ratio of the density of a substance to the density of a given reference material. Specific gravity = 0.8669 (same as density in units of g/cm 3) The units of grams and cubic centimeters are defined in such a way that their density quotient in relation to pure water is 1. Density is the mass of material per unit volume. At 4.0 °C, Normal urine has a specific gravity of 1.03. This calculator converts between various units of salinity. It can be calculated by comparing the weight, mass and density of the given object with water of the same amount at 4 0 C. Specific Gravity Formula is expressed as At 4 degrees Celsius pure water has a density of 1g/mL or 1kg/L and a specific gravity of 1. Density (d) is mass per unit volume of a substance. The formula for specific gravity is: SG = ρ / ρ w Bulk specific gravity of aggregates can be defined as the ratio of oven-dry weight of the aggregate to the bulk volume of the aggregate particles. Specific Gravity of gases is normally calculated with reference to air - and defined as the ratio of the density of the gas to the density of the air - at a specified temperature and pressure. The Specific Gravity can be calculated as SG = ρ gas / ρ air The density of water varies according to temperature and the degree of purity. Calculation of Specific Gravity Specific Gravity = ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unit volume) of a reference substance. However, the user can enter other values for the denominator density. Temperature changes affect the density of water, resulting in differences between density and specific gravity of the material being tested. Specific Gravity gives information about the weight and density of the object. Therefore, specific gravity has no units. Where SG is specific gravity. o It is usually expressed as (g/mL) o The density of water may be expressed as 1 g/mL o Density may be calculated by dividing mass by volume, that is: Density = í µí± í µí± í µí± í µí± (í µí± ) For this example, we will say the specific gravity is 50. Density is very slightly less than specific gravity. SG = ρ / ρW Where SG = specific gravity, ρ = density of the material (kg/m 3 ), ρW = density of water ( kg/m 3 ).

A commonly used value is the specific weight of water on Earth at 4°C, which is 9.807 kN/m 3 or 62.43 lbf/ft 3.. Notice that density is defined in terms of two dissimilar units, mass and volume.
